Soil erosion is one of the important and worldwide environmental and economic issues. High amount of sediments accumulations behind the different structures such as dams requires several attempts to minimize their potential risks. Therefore, some quantified data will be needed in order to recognize those critical areas which requires urgent conservation. Since conventional procedures are time c...

cation exchange capacity and specific surface area are among some of the important soil characteristics the direct measurement of which is laborious, costly and time consuming. therefore, fractal dimension of particle size distribution has been widely studied in relation with many such dynamic and static processes as transmission of water and solutes, water holding capacity, heat storage and co...

water balance components are difficult to measure in short intervals because their measurement is time consuming and costly. therefore, soil-water--plant models can be used for prediction of these components. in this study, to predict grain yield and evaluate water use efficiency, an agro-hydrological model, namely, swap was used. this study covered a 10-years period from 2000-2010. based on th...

background: wilson disease (wd) is caused by numerous pathogenic mutations of the atp7b gene. there are several mutation screening methods that can be used for the diagnosis and carrier detection of wd, however such methods are costly and time-consuming. therefore, other diagnostic methods should be used for urgent situations such as prenatal diagnosis. objective: to report common polymorphisms...
